IMPROVEMENT IN UPRlGHT-PIANO ACTIONS.

Specification forming part of Letters Patent No. 197,526, dated November27, 1877; application filed October 10, 1877.

To all whom it may concern:

Be it known that I, GEORGE WV. NEILL, of Boston, of the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Actions for Upright Piano-Fortes; and do hereby declarethe same to be described in the following specification and representedin the accompanying drawing, which exhibits a side elevation of myimproved action.

My improvementconsists in the combination of a stationary bar and apivoted supportingarm with the back-catehand the fly-supporting arm orbed, all being arranged essentially as set forth.

The advantages of the improvement over most, if not all, ordinary modesheretofore in practice for supporting the back-catch are, that itenables it to better sustain the hammer,

1 and the latter to repeat with more certainty and useful effect.

In the drawings, A denotes the key; 13, the hammer; O, the jack or fly,and D the bed or supporting-arm of such fly. This bed is pivoted to astationary rest or bar, a, the fly being hinged to the bed at its front.The said bed rests on the top of a push-rod, b, which, at

its lower end, is pivoted to a rocker or adjust able lever, c, fixed tothe key.

From the hinge-block of the hammer an arm, (1, projects backward, and isprovided with a head, 0, for the back-catch f to bear against. The wireg of the back-catch extends upward from a sustaining-arm, 71 which,hinged to a stationary bar, 1', rests on the bed D. The back-stop E ofthe fly is arranged over the bar '1 as shown. A strap, F, extends downfrom the hinge-block of the hammer to, and is fixed to, a wire, G,projecting from the bed I).

The key being struck, the fly-bed will force upward the supporting-armof the back-catch, which arm will fallwith the said bed while the keymay be in the act of rising.

I cl.aim

In an upright-piano action, the combination of the straining-bar i andthe pivoted supporting-arm h with the back-catch and the flysupportingarm or bed, all being arranged substantially as set forth.

GEO. WV. NEILL.
